Ogres
The Ogres on Oberon are large (2.25m/7.5 feet tall) humanoids that have resided in Imperial lands since the end of the 1st Century IC.
Initially the Ogres crossed over to Imperial lands from Minosha, most likely as raiding parties. Many Ogres, instead of pillaging, decided to settle and still live along the west coast of Chundria. After the signing of the Treaty of the Eight Thrones the (ever pragmatic) Empire came to an agreement with the Ogres, allowing them to stay in Imperial lands as long as they fought for the Empire when required.
Although they have been used by the Empire as shock troops and brute squads they are not, by nature, an evil or even particularly violent race. OIn fact, most Ogres are quite content to lead an egrarian lifestyle and avoid combat wherever possible. Unfortunately Ogres share a common trait with Orcs which is a tendency to become easily enraged. It is this trait that gives the Ogres their fearsome reputation.
It should be noted that Ogres and Humans, whilst they may be physically compatible, are not known to be capable of producing offspring. Heroes with claims that they are 'half-Ogre' may just be a way to single themselves out, especially if they have great physical strength. A notable example of this phenomena is Boris Da Ax.
Perceptions of Ogres
Two centuries ago, Ogres were treated in the same vein as Orcs are treated now. These days they are commonly regarded as a nuisance that, as long as they stick to their own kind and don't cause trouble, are widely tolerated. This gives Orcbloods some consolation that, given time, they too will be accepted. However, even after 200 hundred years, Ogre and human communities keep a respectable distance from each other and only interact when necessary. Humans and Ogres may not be "enemies" but they most certainly are still not "friends".
